The document describes WEG's System Drive VFD AC Motors, which are designed for variable speed applications and offer benefits such as high overload capacity and expanded speed range. The motors range from 1HP to 1500HP, are TEFC, and can operate at constant torque from zero speed up to their rated speed. They are based on WEG's severe duty motor platforms and insulation systems to provide reliability. The document provides details on standard features, optional features, and WEG's full product line.

System Drive VFD AC Motors
The WEG Systems Drive VFD AC motor raises the bar for customers who demand the best. Benefits
such as very high overload and expanded speed range capabilities increase the value of the product for
many variable speed applications.
The designs are based on the W22 and H-Line Severe Duty motor platforms for outstanding reliability.
What makes this a Systems Drive Motor
g
Constant torque capability to zero speed in standard NEMA frame size TEFC motor
g
High torque designs for wide constant HP capability
g
High short term overload capacities can exceed 200%
g
3 NC thermostats on winding
g
Drive end shaft grounding available (standard 447T and larger )
g
